My im'ention else resides in novel few sures of construction. and in combinations of perisvmaking up a eempiete Welding machine; all hereinafter fuiiy described and particularly pointedout in .ihe appended claims. My invention "will be more readily uude1=- steed by reference t0 the accompanying di'iiwings wherein I have iiiustmted u tube Weiiiug machine made in" acccmiance'with and embodying? iuventieu and wherein: Iaigure l a eiue eievation of said ma chine; 2 is enlarge-(i tap plan View, the burner being IEIZIOVELi. to more clearly show other parts of the machine; Fig.3 is an emerged vertical transverse seci'ionai view on the line 3-3 of Figs. to 9 inclusive are eniez'ejed transverse {SGfi'EiOXES of the vise mechanism i iiustrating various adaptations 'oi' the machine-icthe Wei-fling}; of tubes of difi eren'iei'essfiectional forms, the forms shown in Figs. and 9 being, preferred in cases where the tube is initiaily, given a non-circular cmss-sectien and a ter being" Welded is made circular in form; 1" 10 is 2% detail transverse sectional View 0 the line 10---1O of Fig, 2 showing the Opel tien 0f the vise opening; device; 11 is a perspective viewe'f said device: and Fi i2 is; a horimntz i hunsvei'se seciiou on. line l2-12 of Fig. 4-, showing Lietniis of the cen- VBYQF cimins and vise sections.

In order to carry out my iuvenfiinu '1 con struct :1v machine which has a continuously opera ting mechanism adapted to receive and propel the tube irmgitusiineliy forward at a substantially constant speed, t0 eefipemte with the non-circular tube fer positioning it aeeurutei-y with-I'es wet he a heating zievice, and pieferabiy to nmiutain or cause the nizzii'ztexmnee of suiiieieut pressin'e at the tube semnie iz'oid the tube edges in fixed relation and aid in the formation of the we1d;. I prefer to construct. :1 m: chine which has a reiativeiy stationary Welding burner adept ed to play flame upon the seam of the tube it travels, and, which has an autematie traveling vise arranged in sectimis adapted "I ii mamas of, andtorsionally twist or rotate the lDCOH1-- ing tube-to accurately position or aline'its scam with the burner.

Ks shown in the drawings a frame 2 is provided whereon the operating mechanisms are mounted at a convenient height for use. This inechanisn'i includes the continuously moving vise. A pair of continuous conveyor chains 3, 3, are mounted upon sprocket wheels, 4, 4:, which in turn are carried by transverse shafts, 5,5. lhese chains are arranged to travel in unison at a constant speed and are provid d with a number of )airs of opposed vise blocks or sections 6. he series of OPPOSHI vise blocks constitute what can properly be termed a continuous vise, the blocks being of such length that end-to-end along the upper horizontal portion of the chains they present a lon j continuous gripping or active portion. ower isapplied to move the vise in the direction of the arrow in Figs. 1. and 2 by means of the belt pulley 7', the worm gearing 8 and the train of gears J. The machine is provided with a bed plate 10 upon which the upper I horizontal or active portions of the convever chains run and upon which are secured the devices for causing pressure at the tube seam. Beneath the table and the transverse shafts 5, 5' I arrange a tank 11 to contain .water or other cooling liquid into which the wise blocks pass as they return from the rear to the forward end ofthe machine.

-";l"he water enters through the inlet pipe 11,

at one side of the tank and leaves through the overflow pipe 11 at the other side. 11 represents a valved drain pipe for emptying the tank.

As clearly shown in Figs. 4.- and 5, the jaws 7 of the vise blocks are shaped to conform to the outer contour or shape of the particu iar non-circular tube to be welded. The tube receiving opening l'ietwecn each two jaws is repeated in every other pair of jaws and it is obvious that the extended opening thus formed between the jaws comprising the straightor active portion of the moving vise is a straight opening of lOH-(ll'ClilflI crosssection. As the tube. which these jaws are made to fit is not circular and as a considerable length of the tube is held in the straight portion of the vise. the tube will he automatically straightened tlicreby'and its scam will be presented in a straight line parallel to the edges of the jaws notwithstanding any initial twist or distortionof the tube. In other words, when the end of the non-circular tube passes into the vise that end will he adjusted to the jaws. This action will be repeated in successive portions of the tubing as they are grasped by successive pairs of vise jaws. the vise itself serving to correct the initial irregularities in the seam of the tube. in Figs. 4- and 5 i have illustrated the tube 12 as beirn oval in shape or as having flattened. side portions 13 and more sharpl I curved upper and lower portions 14. It wi l he at once understood, however, that if the tube is of some other cross-sectional shape than the one therein illustrated, the contacting faces of the jaws? will be constructed accordingly as in Figsfi, 7, 8 and 9, where in I have shown tubes of various ,cross sectional shapes. As hereinbefore mentioned his type of machine is designed to weld the seams of tubes formed from a long strip of sheet metal. In the forming process the edges of the strip are brought preferably into butt relation in readiness for welding.

The oval tube illustrated in Figs. 3, 4 and 5 is formed with the longitudinal seam or joint 15 in the middle of one of themore sharply curved portions 14 and when the tube is presented to the welding flame b the vise this side or portion of the tube is turned uppermost.- The machine is provided on its forward end with a stationary guide 16 through which the tube passes to the rise jaws. When the end of the tube is grasped or clan'ipcdby one pair of vise jaws, they carry the tube forward. The succeeding pair of jaws immediately rise intoposition, grasp the portion of the tube immediately following that portion which has been clamped and so onthroughout. the tubing, this operation being continuous.

, Due to various causes, the forming of the strip of metal leaves the tube irregular or wavy and more or less spirally twisted,

that an alined relation must exist at all times during the welding operation so that the weld will always occur exactly at the seam. I correct the irregularities of the seam by arranging the vise to rotate or torsionally twist the tube as hereinbefore explained and thereby conform the seam to the position of the burner. inent offers the additional advantage that the vise acts to straighten .the tube and prcvent it from warping; or becoming distorted due to the heat from the burner. I form the jaws so that they grasp the tubing in such a manner as to both straigl'iten and twist the tube, as may be necessary, thereby automatically positioning the scam of the tube accurately in alineinent with the weld ing flame. It will be at once apparent that the pressure to twist the tube can best be applied adjacent to'its upper and lower parts and I therefore form the clamping surfaces of the jaws to grip the tube at least at these points although it is better that they al nostsurround the tube, ieaving a sufficient portion of the metal adjacent the seamexposed for the weld. In this manner there will be no tendency of the vise to crush or distort the walls of the tube This arrangememes as the jaws are forced into clamping contudinal seam at one end of this axis so that the tubing may be positioned with its major axis vertical and the seam uppermost. With this arrangement the maxi mum twisting and straightening; effort can be exerted upon the tube. Obviously, how'- ever, the seam may be formed at portion of the tube and the machine construct ed to adapt it thereto. The oval Iorni is well adapted to the manufacture e2: tremely accurate circular tubing for the reason that the strip metal can be initially formed into an oval tube in which COTlflltionpthe seam may be accurately Wi-DlCieCl herein described. The tube may then be subjected to the pressure oi. ordinary circular dies (not shown) and thereby given a. perfect circular form.

Having now explained the purpose uml nature of my invention, together with the essential elements of the machine for ourrying out these functions, I Wili describe in detail the various parts of the said nuichine.

The vise blocks 6 are carried by pins or rods 19 which extend across from chain to chain ancl which ere reciucecl at their ends 20 to form chain rivets. Each pair of opposed 'bloclts is carried upon two of the pins 19 and is freely movable laterally thereon so that they can be moved lZQWll'i'Kl each other to clamp the tube and from each other to free the tube.

by means of a. transverse dowel pin 21 which is mounted in holesor pockets 22 in the lower parts of the blocks (Figs. l and 12). The combined depth of the two-cowesponcling hoies is considerably more than the length of the pin 2-1, this difference ellowing room for compression springs in the holes at the curls of the pin 21. The springs resiliently hold. the vise blocks (3 at the outward, limit of their movement so that us the vise moves the blocks will pass freely into ulineinent with the tube i 2.). I provide pressure mechanism r the purpose of causing these blocks to close successively andclemp the tube and at the some time correct any irregularities in the tube as previously explained. This pressure mechanism consists of cum bars or guirles 24 our] ucljustnbly mounted upon the face of the bed plate 01" platen i0. and For the purpose oi reducing the friction and consequently the power necessary to draw the chains with their vise l')lf)[l(. through between the guides, i arrange a se ries bf auti-iriction rollers 20 in the. cuteencls of the blo ks arranged to upon Each pair of vise blocks is normally held open or separated pifcssure i so. ostunt the inner cam faces 24' and 25 of the guides respectively. I melts these guides adjustable from/and toward the tube forthe purpose of widening the range of the machine and adapting it to tubes of different sizes and shapes. The guide 24.- is held upon the platen by means of the bolts 27, which screw into the bed. plate 10, the guide being provided with slotted holes 28 to receive the bolts and allow for adjustment. This guide hclcl against lateral pressure by means of the horizontal set screws 29 which are moi'intecl in lugs 30 forming part of the bed plate 1%). The opposite guide 25 is held in a, similar manner exceptthat it is nottightly clamped to the bed plate but is held down by the bolts 31 which are threaded into the bed plate and held rigid. by the jam nuts 32. This guide .25 is movable from and toward the guide 2%, and lforce it towarcl the guide 2% by means. of compression springs which are mounted in pockets formed in the outer edge of the guicle and which are interposed between set screws mounted. in lugs 36 similar to the lugslll), suitable i vashers be: 5; provided upon which the the set screws bear. This man ner of mounting the guides provides an adjusteble compressive force upon tube at all times and. permits the machine to operate upon the tube without undue friction and with clue regulation with respect to the expansion of the tube v'rhen heated.

t will now be clear that when the tube is engaged. by the vise jaws-end carried. beneath the flame played upon the seam by the Weldin torch 1?,tl1e pressure of the vise jaws against the tube will hold. the tube edges in butt relation and cause sufiicicnt to complete the weld. As the tube advances thii'iugh the machine the welcl will become cool enough. so that the longituclinsl seem will not again Whentlie tube is releasefi from. the wee jaws. The

and 25 of the 3 surfaces 7 and 25, seen in Fig. 2, are by tralglit anti parallel through.

part of their length. Their rem ouinner out the 5.;

.i orvverd 38, however, are ilerecl outwuivll i the purnoee of oerniitting the vise blocks with the. wion rollers. which when free from. the guides are normally held sepereteel, to freely enter bes This spreading and con H o;' the pairs of vise jaws permits the jaws to move upwardly past the sides oi the. tube uncl close properly upon the tube The guides 2% and terminate at their rear ends 39 just before the chains commence to travel downwardly around the sprocket Wheels i, ccnserpientiy thewise. ions are this point freeto be separated by the ccui'g'ires n springs 23 ancl to be mm on urdly to disengage thetube. In

' they exert a compression force upon the tube, carrying the tube with them with its seam positioned beneath the fiame, and that at the rear end of the machine they successively open and release the tube. lit is quite apparent that various welding means may be used for heating the tube instead of the torch 17, but I prefer for a number of reasons to use a gas welding flame arranged to play upon the seam of the tube-as it travels beneath said ilanie.- The torch 1'? admirably suits the purpose. The torch shown is of well known form using a mixture of. oxygen and acetylene gases which burn with an extremely hot flame at the nozzle 46. This flame may be described as onsisting of a fine, narrow Welding flame of extreme heat impinging directly upon the seam of the tube, and a forwardly extending corona or" lesser heat and larger than the welding flame- The corona serves to preheat the tube in advance of the welding flame, raising the temperature of the tube to nearly the Welding temperature and thus enabling the welding portion of the.

llamc to complete the Weld quickly. Thus the tube seam is welded as fast as the tube travels. The speed at which the Weld is performed is governed to a great extent by the temperature of the flame and its dis tauce 'l'iw ll] the tube. This makes it desirable to have considerable regulation for the torch so that the maximum rate of welding may be obtained, and for the purposes of examination and repair. I therefore pro vide an adjustable holder 18 by which it is possible to attain every needful adjustment. This holder is supported in a frame ositioncd over the vise about the middle t ereol. This frame corm'n'ises-a pair of standards l-l rising from the opposite sides of the bed plate 10 and carrying in their up per ends :1 transverse rod or shaft 42. The torch is carried in the outer end of a lever 3 which is pivotally mounted to swing from and toward the tube upon a l'iracliet 44, which in turn is clamped upon the shaft lil by means of the clamping bolt 45. The nozzlc -l(5 of the torch is atthe lower end thereof and is pointed diagonally downward t ward the tube at an angle of about 4-3 degrees so to project its flame forwardly. Tl

lil whereby the nozzle can be swung: erally and the lame accurately impinged iv. torch is rotativcly mounted in the lever menses directly upon the seam of the tube. By-

the lame away from the tube for the purpose of examination and repair. In order to conserve the heat of the flame and con fine the metal adjacent to the seam so that the remaining portions of the tube will not be unnecessarily heated, I provide suitable guards or heat insulators d7 arranged loingitudinally of the tube and on each side, of the flame. l mount these guards or heat insulators in the free end of the bracket 48 which is secured to and carried by a transverse bracket 4-9 forming a part or" the frame of the machine. Tlhis bracket 48 is bolted to the bracket 49 so that it can be readily removed to facilitate repairs.

As many modifications of my invention will readily suggest themselves to one skilled in the art, 1 do not limit or confine my invention to the specific structures or combinations or parts herein shown and. described, except as required by express lirnitations in the claims hereunto appended.

it shouldbe noted. that portions of the subject matter of this specification are not specifically claimed in this case, but are both described and claimed in applications filed by me which have matured into Patent No. 1,627,864 issued May 28, 1912, and entitled Continuous processes of manufacturing metal tubing, and No. 1,02?,865 issued May 28, 1912, entitled Continuous tube mill; and also in my pending applicationsSerial No. (389,093 and Serial No. 689,095, both filed April 6, 1912.
